Answer 2

Answer:

3/13

Step-by-step explanation:

7/9  +3/13

=  7 × 13/9 × 13   +   3×9 /13 × 9

= 91/117+27/117

= 91 + 27/117

= 118/117

Would be the same as

3/13+7/9

= 3 × 9/13 × 9    +    7 × 13/9 × 13

= 27/117+91/117

= 27 + 91/117

= 118/117

So, the answer is

 7/9 +  3/13   = 3/13 + 7/9
